Matter integration

[Karsten Sperling]

Hi Lukas,

Exciting to see Matter being picked up and getting contributions in the open source space like this :-)

In terms of the build, I’ve did a bit of work on the Matter SDK side to add a “configure” script that aims to provide a somewhat cleaner interface to an external build system like OpenWrt than the raw GN / pigweed build provides. Feel free to reach out on the Matter SDK repo if you’re running into issues with it.

Thanks, Karsten

That does not seem to be necessary any more - I am very glad to see the devel/gn package, and will try to build p44mbrd this way and then create an openwrt package for it.

So I probably cannot help much in the latter field, but still hope I might be able to contribute from general openwrt / matter experience.

Development on this has recently started at https://github.com/project-chip/matter-openwrt.  We’re using OpenWRT as a platform because of its open nature and great hardware support.  I wanted to reach out to make the OpenWRT developer community aware of this effort, and to invite you to collaborate with us if you’re interested.

Getting this PR merged would help us to get the Matter SDK and related software to build cleanly under OpenWRT.
